At a quick glance, the syntax looks similar to the one used by Quartz Scheduler, so you can almost use this: https://freeformatter.com/cron-expression-generator-quartz.h...
I say "almost" because Quartz Scheduler expressions have one additional field: seconds. And there are more than likely differences in how nontrivial expressions and corner cases are handled by different tools.
